Easy to install and compatible with 95% of indirect electronic fuel injection engines manufactured after 1998.
Attention! Our ethanol kits are not compatible with vehicles equipped with monopoint injection, direct injection, or carburetors.
EcoFuelBox PRO+ is the most advanced ethanol kit on the market, equipped with a powerful microcontroller and firmware with machine learning algorithm, providing unmatched fuel efficiency and performance.
External temperature sensor (magnetic) allows the kit to start your engine easily even in very cold winters, while the fuel sensor (ethanol sensor) allows the kit to monitor the ethanol level in the fuel and adjust the air/fuel ratio in real-time for better fuel economy.
The ease of installation and use, along with the ability to adjust settings, make our E85 ethanol kits suitable for both individuals and professional installers looking for a hassle-free conversion of their vehicles to E85 ethanol.
✔️ Designed, developed, and manufactured in FRANCE.
✔️ Covered by a 3-year warranty.
✔️ Ethanol Kit compliant with CE standards and directives: EMC 2004/108/CE, EN61000-6-1: 2007, EN61000-6-3: 2007, AEC-Q100
✔️ Reduces your fuel budget by 50% per tank with E85 (depending on local ethanol prices).
✔️ 100% automatic, allowing the vehicle to run on E85 ethanol, SP95/SP98, or a blend of these two fuels.
✔️ Cold start system with remote sensor for easy starting.
✔️ Easy installation, the kit can be mounted in 25-60 minutes (depending on the vehicle). No need to cut or solder vehicle wires.
Adjustable Parameters:
✔️ Air/fuel mixture ratio during cold start.
✔️ Air/fuel mixture ratio during warm start.
✔️ Air/fuel mixture ratio after starting.
Please note that after installing the EcoFuelBox PRO or PRO+ bioethanol conversion kit, in 98% of cases, no adjustment of the box is required as our conversion kit will automatically adapt to your vehicle. However, in cases where adjustment may be necessary (e.g., if certain car sensors are faulty), you can adjust the necessary settings in 5 to 10 minutes. Whereas with other kits available on the market, in addition to the initial cost, you will have to spend a lot of time and money to make your car run on ethanol.

Aucun souci, le boîtier marche très bien sur ma Volvo XC60. C'est le second boîtier EcoFuelBox que j'achète sur ce site. Service client au top. Évitez les kits chinois que vous trouvez à 89-169 euros sur d'autres sites. Ils ne fonctionnent pas du tout ou tombent en panne très rapidement.
Le radin paie deux fois :)
I was searching for quite a long time for a 5-cylinder kit here in Sweden but couldn't find a good one. Fortunately, my friend, who has had an EcoFuelBox installed on his Ford F150 for almost 8 years, advised me to contact EcoFuelBox to check if they manufacture 5-cylinder kits for my Volvo S40 2.4i. It took me about one hour to install the kit, and voila, my Volvo is now a flex-fuel car :)
I'm only giving 4 stars because the delivery by UPS was a real mess.
Très bon kit éthanol. Livré rapidement. Facile à installer sur une Volvo S40 II T5 de 2007. Quatre pleins et aucun problème. Pas de voyant, RAS. J'ai même l'impression d'avoir gagné en puissance.
